. ART OF MAKING lMlTATiQN STONE FRONTS.

To all} whom it may concern.-

Be it known thatI, ERNEST G. KEMPER, a

citizen ofthe United States, and a resident of St. Louis, State ofMissouri, have invented certain new and useful Improvements in the Artof Making Imitation-Stone Fronts, of which the following is aspecification.

This invention relates to improvements in the art of makingimitation-stone fronts; and it consists in the novel arrangement,construction, and combination of parts, as will be fully hereinafterdescribed and claimed.

The object of my invention is to construct panels or plates provided.with suitable flanges whereby one maybe attached to and sup orted to theother and provided with a sur' ace designed to form imitation stonefront on a wall of concrete.

A further object of my invention is to build a wall of concrete on theface ofwhich is imprinted an imitation-stone surface, which is done byapplying a plurality of plates having faces to imitate stone, and afterthe wall of cement has sufliciently set the plates can be removed. I

In the drawings, Figure 1 is a perspective view of a portion of a wall,showing my invention in relative position during the art of formingthestone front. Fig. 2 is a vertical sectional view of a portion of thewall, show- Fig. 3 is a per spective view of a plate showing theadjustable feature'. Fig. 4 is a perspective view with parts broken awayand in section of a plate with its flange adjustable- Fig. 5 is a detailverticalsectional view of the same, showing the use of the adjustableflange. In the construction of myinvention I provide a plate of sheetmetal 6, rovidedwith flanges 7, 8, 9, and 10. The ace 11, out of whichthese flanges are formed, is rov'ided with a surface bent and shaped toorm-the configuration of a' stone or builders rock.

The flanges 8 and 9 are provided with rightangular projecting flanges 12and 13. These flanges are formed integral and bent out of the samemateriaL'and the flange 13 at its center is provided with a recess 14,through which a wire 15 is adapted to be passed and supported by meansof a. pin 16, passing through the loop formed on the ends of the wire.The purpose of the wire 15 is to retain the plates in parallel positionwhen the con-, crete is placed "between them.

by means of the flan es, are interlocked, as

upon the other are staggered, as in the mauner of laying rock or brick,so that the ends of the plates are in alinement with the. recesses 141,thus forminga support for each other.

In building a wall of this character the latcs are built one upon theother to a heig t desired and placed apartat a width sufficient for thethickness of the wall to be built. The.

rear or inner plates 17 are similar in constanction, but have theircontacting faces corrugated, as indicated by the numeral 18. I'Vhen thewall is built to the height" desired, the concrete is lodged between theplates and the same coming in contact with the surfaces of these lat-eswill form on the front surface a stone ace, while in the rear will beformed a corrugatedface, upon which is applied the plaster for theinterior of the room, and by means of the corrugations the plaster wilhave a perfect and-rigid adhering surface.

In instances where it is desired to use a short pl at'e for example, atthe corner of the wall-and to dispense with cutting the plate to fitsuch requirements I design a plate, as shown in'Fig' 3, composed oftwosections 19 and 20. Section 19 is provided with two projecting pins21, which operate through slots 22, formed in the section 20, and onthese ins are placed thumb-nuts 23, which by tig tening the same willrigidly secure toflanges are rigidly secured together when adjusted. Toconstruct a wall of this character, especially where it is desired toextend it to a great height, stiffening-tubes 28 are placed atintervals. throughout the walls, and around these is located theconcrete which forms the wall, and after the plates have been removedfrom the outer surface of the wall the im rint .of the faces thereofresembles that of roc asshown by the numeral 29.

Having fully described my invention, what I claim, and desire to havesecured to me by Letters Patent, is-

1. A'd'evice of the character described comprising a plate, rectangularflanges formed on said plate, a right-angular projection formed on twoof said flanges, one of said projections I rising plates havingirregular surfaces to provided with a recess for the insertion of a ormthe configuration of stone, flang Wire, and an irregular surface formedon the 1519339 to resemble rock. substantially as specie I v 2. A deviceof the character described comprisin plates provided with flanges andrectangu ar projections whereby one late may be placed against theother, one'ofsaid rec'- tangular projections provided with a recessthrough'whi'ch is passed a wire for locking the same together when inosition; and having faces to imitate the 'co g-uration of-ston'e on abody of cement placed between them, substantially as s ecified'-.

3. A device of t e character described comes formed integral with saidplate, rectangu ar proj ections formed on two of said flanges, andadjusting means wherebysaid plate may be shortened if desired, andanadjustable flan e whereby an ofiset may be formed on the wa l,substantially as specified.

In testimony whereof I have signed my 2 5,

name to this specification in presence oftwo subscribing witnesses.
